LAMP-TORCH.

SPECIFICATION `forming part of Letters Patent No. 224,830, datedFebruary 24, 1880. l Application filed December 18, 1879.

l of the city of Gohoes, conntyof Albany, and

Sta-te of New York', have invented a new and usefulImprovementinLamp-Torches, of which the following is a specification.

My invention relates to thatclass of devices which are used to light thegas burners and lamps employed in factories and mills, where it isessential to the safety of surroundings, as regards communicating lireto them, that the torch shall be inclosedby a protecting surroundingscreen.

My invention consists in combining with a lamp having a stati' andhandle a surrounding screen constructed with a perforated and coneformedtop, open atthe apex, having air-sup plying apertures at the bottom, andactuated so as to be drawn down' around the lamp by means of afinger-hook arranged upon a sliding cylinder which surrounds the staff.The finger-hook is connected with the screen, and acts, when grasped bythe finger, against the force of a spiral spring upon the staff, bymeans of which spring the screen is caused to rise and return when thegrasp of the lingerhoolr is released, the object being to provide ameans by which the lighted wick will be near the top of the screen forlighting purposes when the latter is drawn down, and by which the screenwill automaticallybereturned -to surround the lighted wick lower down inthe inclosure formed by the screen when the finger-grasp of the hook isreleased.

In the accompanyingxdrawings there are two igures illustrating myinvention, in both of which the same reference-letters refer to the sameparts. y Figure 1 shows, in elevation, a view of a lamp-torch containingmy invention and the manner of grasping it so as to use the fingerhookfor pulling down the screen. Fig. 2 illustrates, in vertical section,the same device, and, by means of a dottedline, the relative position ofthe lamp and screen when the latter is drawn down around the former andagainst the action of the spring.

The several parts composing the device are designated byreferenceLletters, as follows: L denotes the lamp, having the wick-tubeThe operation of the combined parts'com?n posing the device is asfollows: When the handle J is grasped the screen is pulled down aroundthe lamp bythe finger of the operator, as shown in Fig. l and the dottedline in Fig. 2, and it brings the open top near the wick, andsufficiently so to ignite the gas escaping from an opened burner. Whenthis is done the finger-hook is released, and then, by the action ofthespring, the screen rises so as to inclose and surround the lamp, asshown in Fig. 2, in the position other than the one shown `by the dottedline.

I am well aware that lamp-torches have been made having a protectingscreen which could be drawn down around the lamp, so as to have the wickproject from the top of the screen.

I am also aware that it is not new to combine a lamp andinclosing-screen open at the top, and with a spiral spring surroundingthe handle, and provided with a stop, so that when the screen waspressed against the burner-base of a lamp-post or other object thescreen would be forced back against the spring, with the wick at theopening.

My improvement upon these older devices consists in combining with thelamp-screen and spring a means to move the screen, to be operated fromthe hand of the person grasping the device.

While I have shown and illustrated. a sliding screen having acone-formed perforated top, I do not desire to limit my invention to theprecise form shown, for the combined spring sliding tube and linger-hookas arranged would perform the same office in the same manner, whether acone-formed screen was used or one of some other form having the sameconnection was employed.

IOO

`I claim, and desire to secure by Letters Pat- Having thus described myinvention, what ent, is-

1. A lamp-torch having a surrounding sliding screen inclosing theWick-tube and lamp, and a spiral spring surrounding the staffv betweenthe screen and handle, in combination with a finger-hook connected tothe screen, by means of Which the latter may be drawn down around theWick-tube and lamp against the force of the spring, it (the screw) beingautomatically returned when the grasp of the tinger-hook is released,substantially as shown and described.

2. In a lamptorch, a surrounding screen having a cone-formed perforatedtop and airsupplying apertures at its base, in eombination with a spiralspring surrounding the staff, l

and an exterior sliding cylinder surrounding the spring and staff andconnected to the screen at its base, With a finger-hook upon the slidingcylinder, by which, when the staff is grasped, the screen may be drawndown around the lamp and Wick to ignite gas and other material burnedfor illumination, and arranged substantially as set forth, so that whenthe iinger-hook is released the screen will be pushed up higher aroundthe lamp by the force of the spring, as herein shown and described. f
